Represents a key image by identifying DICOM selection data (study, series and instance) for R4. Use this profile when the key image is a reference to DICOM content rather than image content represented in a Media resource.

A key image is an image, or a specific frame within an image, that the imaging clinician has selected as particularly relevant to the report — for example an image that best demonstrates a finding, supports the impression, or is useful for comparison and follow-up. In radiology a study can contain hundreds or thousands of instances, so flagging key images helps the referring physician and other readers quickly locate the most significant images. In DICOM, key images are typically captured using a Key Object Selection (KOS) document, described by Key Object Selection, TID 2010 in DICOM PS3.16.

Representation of Key Images

Key images can be represented either as image content or as a reference to DICOM selection data:

• Media (MediaKeyImageEuImaging) — the key image as image content.
• ImagingSelection (ImagingSelectionKeyImageEuImaging) — the key image identified using DICOM selection data. In this R4 IG the ImagingSelection is implemented on a Basic resource with a cross-version extension backporting the R5 ImagingSelection structure.

ImagingSelection is more DICOM oriented and relates to DICOM identifiers. Media represents the image content and contains information such as its size, format and duration. The eHN Imaging Studies and Reports guidelines requires information on the size, format and duration; these data elements are provided by the Attachment in Media.content.

This IG uses Media in R4 for image content, and ImagingSelection when the key image is identified using DICOM selection data (for example, to state that an image can come from a Procedure Phase).

The ImagingSelection resource points to DICOM data. The DICOM instance data also holds the data required by the eHN Imaging Studies and Reports, so the client can retrieve the information from the DICOM source data. Access to the imaging data can be direct or through a web based image viewer; a scenario supported by ImagingSelection requires access to the DICOM identifiers and a WADO endpoint.

Media resources refer to the image data directly, either by including it in the Attachment or by linking to it. The report may also refer to key images such as charts or PDFs that are not stored in a DICOM PACS; Media supports this case.

Key images can be represented by ImagingSelection or Media resources. When using Media to represent a DICOM artifact, it carries an identifier corresponding to the SOP instance, series or study it represents. In the case of ImagingSelection these values are represented as fields in the resource.

Required Imaging Study Reference

The profile SHALL contain the derivedFrom[study] slice exactly once. The slice SHALL reference the ImagingStudyEuImaging profile:

• extension[derivedFrom][study].value[x] SHALL be a reference to ImagingStudyEuImaging.

Performer Requirements

When performer information is present, the profile SHALL distinguish it using the following slices:

• performer[pracRole] MAY occur once. When present, its function SHALL be fixed to PRF (Performer), and its actor SHALL reference [[[EuPractitionerRole]]].
• performer[device] MAY occur once. When present, its function SHALL be fixed to DEV (Device), and its actor SHALL reference Device: Imaging Device.

These slices and their function-to-actor correlation are enforced in R5. R4 retains the aggregate cross-version performer constraints until the required publisher and validator support is available.

Tracked by FHIR-57776: R4 profiling of inherited cross-version extensions is valid in principle, but the Basic.extension:derivedFrom and Basic.extension:performer cases expose current tooling limitations. The performer reslice must declare its added discriminators on the unnamed slicing entry while retaining the inherited discriminator, and org.hl7.fhir.core must resolve extension(url) discriminators against inline sub-extensions. The correlated performer reslice remains deferred; the current aggregate performer constraints remain the production representation until a publisher release includes FHIR core fix #2599 and its validator test case.
